Fully Automatic Gas Adsorption Constant Tester

Fully Automatic Gas Adsorption Constant Measuring InstrumentWY-98A

Product Introduction

The Fully Automatic Gas Adsorption Constant Measuring Instrument (hereinafter referred to as the instrument) is primarily used in the process of determining coal mine gas content to measure the adsorption constants (a, b values) of coal for gas. Based on these values, the actual gas pressure measured underground can be used to calculate the gas content per ton of coal seam.

Usage Environment and Performance Characteristics

1. Usage Environment

（1）Operating temperature: 0～40℃;

（2）Relative humidity: ≤95%;

（3）Atmospheric pressure: 80 KPa～106 KPa;

（4）Mechanical environment: Locations without significant vibration and impact, and no strong magnetic field interference around the laboratory.

2. Performance Characteristics

The device is designed with an integrated concept, incorporating the main systems of vacuum degassing and high-pressure adsorption internally. This changes the traditional decentralized operation mode, improving testing efficiency and accuracy;

The device has a high degree of intelligent operation, automating and intelligently programming the experimental process into the system control software. It is easy to operate, with scientific and accurate data, reducing human error;

The entire measurement process is automatically controlled without manual operation; the constant temperature water bath automatically drains water and features a water level indicator;

Computer-controlled data chart collection, customizable printing of experimental reports and experimental charts;

The high-pressure adsorption process is controlled by solenoid valves, automatically adjusting different pressure points and capturing real-time data;

The data analysis software features a user-friendly interface design, is simple and easy to operate, automatically outputs data results, and automatically fits the isothermal adsorption curve.
